function above() is not working in script, but I can use it in straight table.
I have one more problem. I noted that if in tabel with EX_RATE exchange rate don't exist then I can't use it as key.
Please, look to example below. In straight table 'ORDER VALUE' I would like to have position for date 20111017 and currency EUR,
which consist in column exchange rate value from day before (in this case from 20111014).
